I presume you mean log in to Tivo problems? Though I was having the problem last night of being able to stream/download maybe one thing.. then any future attempts wouldn't do anything. Rebooting the Tivo Stream seemed to fix it for one more attempt..

This was a problem at least one other person had described earlier that I hadn't seen.

Even trying the 'test streaming' option would show 5 4 3 2 1 5 4 3 2 1 etc forever..
I will play with it some more, maybe this weekend (though trying to use it in the meantime too).
